Has anyone had any experience with the magnum chain & lock from Abus? How about the Kryptonite locks or the Cobralinks lock? Also any information on ground anchors? I recently purchased a KTM200exc & want to do everything I can to prevent it from being stolen. My last bike (KDX200) was stolen in August from my garage. I have been looking at these different brands, but would like some user opinions & ideas. Thanks, Tom
